RESYS P40 panel mount type A differential relay (earth leakage protection)

RESYS M40 earth leakage relays associated with a remote trip breaking device (automatic power breaking), provide the following functions:

• Protection against indirect contact
• Limitation of leakage currents

They also preventively monitor electrical installations via a (configurable) pre-alarm function or when used as a signalling relay.

Features:

• Positive or negative security
• Panel mount (48 x 48 mm)
• 2 relays with configurable function (alarm or pre-alarm at 50% (I△n)
• Adjustment of I△n: 0.03 - 0.1 - 0.3 - 0.5 - 1 - 3 - 5 - 10 - 30A
• Time delay: 0 - 0.06 - 0.15 - 0.30 - 0.50 - 0.80 - 1 - 4 - 10 second
• LED bargraph provides real-time display of leakage currents
• Tripping accuracy by TRMS measurement (improves immunity to nuisance tripping)
